CO2 Glue: Green Epoxy-like Adhesives

For more information, contact techtransfer@netl.doe.gov

This adhesive is a "green," environmentally friendly epoxy that utilizes inexpensive CO2 as a starting material, consists

• f composites that can be cured either thermally or with

light, and has a scalable, high yield manufacturing process.

The Summary

Problems with existing epoxies:

• They create volatile emissions

that are toxic

• They require poisonous

chemistries

• They require environmentally

nasty chemistries

• They typically require a specific

type of curing (toughening/ hardening in material creation process): either heat or light

• They tend to be made from

petrochemicals

The Problem

• Excellent adhesive properties

– Exceptionally well with glass and metal

• Environmentally friendly

– No isocyanates – Solvent free – Uses CO2 as one of its components

• Simple chemistry, using a mix and cure

method to create

• UV or thermal curing
• Can be transparent or light yellow in

color

• Mixes well with silica gel

– Flow properties can be modified easily

• Made from the off the shelf,

commercially available components

• An environmentally friendly super glue
• Should cost less to make

The Solution: An Environmentally Friendly Superglue

• The global adhesives market estimated to be worth

$21,527.0 million in 2010 and is expected to reach $28,659 million by 20161

• The specialty adhesives market is valued at $2.4 billion.

The Opportunity

• 1. Global Adhesives and Sealants Market by Type, Applications, Trends, and Forecasts (2011-2016)
• 2. http://www.freedoniagroup.com/Specialty-Adhesives.html

The adhesive has potential for use in the following markets:

• Transportation: Marine,

Aerospace, Automotive

– Glass and metal joints – New composites for automotives, aircraft, boats, and housing requires better adhesive/binder properties (decreases weight)

• Automotive manufacturers
• Recreational sporting good

producers

• Electronics – anything with a

printed circuit board

• Military
• Building materials

• Used aluminum plates
• Applied 1 square inch of adhesive (7-8 mg)
• Fully suspended the plates with 125 lbs
